Current pest control operations

Signal Hill rodent control programme

April 2026 - June 2028

Dunedin City Council (DCC) contractors are undertaking an intensive rodent control operation at Signal Hill Reserve.

The two introduced European rat species in New Zealand (Ship and Norway) pose a major threat to our native flora and fauna due to their rapid breeding rates, destructive foraging behaviours and appetites.

Rodent bait stations containing Double Tap are situated off all main public walking tracks within the reserve. Bait is secured within the locked stations preventing spillage.

Double Tap is a unique, cost-effective and fast-acting toxic bait that is highly palatable for rats. It is a combination of Diphacinone, and Cholecalciferol (vitamin D3).

Please do not touch the bait stations.

Warning signs are placed at all reserve entry points.

Risks to dogs

Whilst the risk to dogs is low, please ensure you:

Keep them on a lead around bait stations
Do not allow them to scavenge dead animals or baits
Stick to main walking tracks

If you suspect your dog has consumed bait, seek urgent veterinary advice.

Environmental effects

Double Tap residues are unlikely to be found in water as bait is placed inside bait stations and clear from streams and waterways. Cholecalciferol does not persist in the environment at all, while Diphacinone is a ‘low residue’ compound.

Flagstaff rodent control operation

March 2025 - March 2028

Contractors are undertaking an intensive rodent control operation across 10 hectares of the Flagstaff Scenic Reserve to help protect the native biodiversity within the area.

The operational area spans from the Firebreak Track and Pineapple Track near the top of Flagstaff and the Ben Rudd Panorama and Seat.

The control methods used are rodent snap traps and diphacinone bait blocks contained in bait boxes to ensure the safety of non-target species. Warning signs have been placed across the area with detailed information about the toxin. All devices are located off main walking tracks.

Please do not touch the control devices.
